Rob Kardashian is refusing to take his recent diabetes diagnosis seriously and is refusing to alter his unhealthy lifestyle.

Sources say the Kardashian klan are deeply worried about overweight Rob, desperately fearing for his health.

It was thought the 28-year-old would shake up his lifestyle after being admitted to hospital and being diagnosed with type 2 diabetes. According to TMZ ex sock designer Rob's condition is so serious he has to inject himself with insulin once a day.

Sources told TMZ: "Problem is, Rob is halfhearted about the whole thing and not committing to the diet or exercise, and the family is worried his condition will worsen and his life will be in peril."

Although his mum Kris seems to think Rob will bounce back - and come back on Keeping Up With The Kardashians.

Speaking at the Architects of Change: The Conversation Series event, she told Maria Shriver: "He wants to still come back and shoot the show, he just wants to feel good.

"It's not that he doesn't want to be on the show, it's just he wasn't feeling good."

She added that he's round "every day", and going on a break last year was the right decision for him in regards to his life and being on camera.

She said: "I think Rob enjoys all the family stuff we do. He has his business, his sock line and his stuff. But I think that it was just the perfect time for him to take like a little hiatus.

"We said, ‘Just get well. Feel better.' He was depressed and just wasn't feeling good and didn't know why."

It comes after reports the family aren't planning an intervention following his recent health scare.

Shrugging off reports he is cutting off contact from the family, sources said: "He for sure talks to Kris. And Kendall and Kylie Jenner have no beef.

"Not sure about others, but they all, I believe, have showed social media love for some time."

His sister Khloe posted a sweet message on Instagram last month alongside a picture of him kissing her on the cheek.

She wrote: "If only you could see yourself through my eyes! I'll forever be obsessed with you! My one and only! #MyAce."

In October Khloe opened up about her relationship with her brother, saying: "He's such a great guy. That's also what's so infuriating. He's charming, charismatic, everything. But I'm like, where is your will to live? Where is your will to live life? Let's be around people!"
